Abstract

In this chapter, we present a parametric method for generating a super-resolution image from a sequence consisting of blurred and noisy observations. The high resolution image is modeled as a Markov random field (MRF) and a maximum a posteriori (MAP) estimation technique is used for super-resolution restoration. Unlike other super-resolution imaging methods, the proposed technique does not require sub-pixel registration of given observations. A simple gradient descent method is used to optimize the cost. The discontinuities in the intensity process can be preserved by introducing suitable line processes. Superiority of this technique to standard methods of image interpolation is illustrated. The motivation for using blur as a cue is also explained.
